No Matlab Livelink response after loading model to Matlab

Hi there,

I have a large Comsol 4.3a model with size almost 50 GB. I would like to run it through MatLab to export all solution data from parametric sweep simulation with almost 1,300 parameter combinations. The problem is that MatLab cannot step to the next script even though its status is busy after finishing loading the model using the following script.

addpath '/cluster/cloud/comsol-43a/mli'
import com.comsol.model.*
import com.comsol.model.util.*

mphstart
ModelUtil.showProgress(true);
model=mphload();

I'm guessing that the model size is too large and there is some limitation on Java about size in the settings. Does anyone know how to solve this problem?

Thanks,
